Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the disclosure is provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.

Throughout the disclosure, when a part “includes” an element, it is to be understood that the part additionally includes other elements rather than excluding other elements as long as there is no particular opposing recitation. In addition, the terms, such as “ . . . unit”, “-or”, “module”, or the like used in the disclosure indicate an unit which processes at least one function or motion, and the unit may be implemented as hardware or software or by a combination of hardware and software.

Embodiments will now be described more fully with reference to the accompanying drawings so that those of ordinary skill in the art may practice the embodiments without any difficulty. However, the various embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein.

Hereinafter, various embodiments will be described with reference to the accompanying drawings.

A robot 1 (FIGS. 1 and 17 ) described herein may include an electronic apparatus 100 (FIGS. 15 to 17 ) for assisting or controlling movement of the robot 1 (hereinafter referred as the electronic apparatus 100). The electronic apparatus 100 according to an embodiment may be included in the robot 1 (e.g., a robot cleaner) to operate and thus may autonomously move.

FIG. 1 is a diagram illustrating a procedure of how an electronic apparatus for assisting movement of a robot operates according to an embodiment of the disclosure.

Referring to FIG. 1 , while the robot 1 autonomously moving moves according to an embodiment of the disclosure, an unable-to-move situation may occur. The unable-to-move situation according to an embodiment may be a situation in which the robot 1 including the electronic apparatus 100 stops moving due to an external element (e.g., being stuck due to a material, a shape, and a curve of the floor, a structure, and the like) contacted while autonomously moving and is unable to restart moving via autonomous control by the robot 1.

For example, while moving, the robot cleaner may become unable to move any longer due to a material or a shape of the floor, or may happen to enter underneath furniture, such as a chair and be stuck and thus may become unable to move any longer.

The electronic apparatus 100 according to an embodiment may move while capturing a surrounding image by using a sensor 110 (FIGS. 15 and 16 ), and when an unable-to-move situation in which the electronic apparatus 100 is stuck underneath a structure 15 (e.g., a chair) and is unable to move any longer occurs, may learn the unable-to-move situation by using a data recognition model based on a neural network, such as a deep neural network (DNN). By learning the unable-to-move situation, the electronic apparatus 100 may pre-estimate occurrence of the unable-to-move situation before the same unable-to-move situation occurs subsequently, and may move by changing a moving path to prevent occurrence of the unable-to-move situation.

According to an embodiment of the disclosure, through learning of an unable-to-move situation, the electronic apparatus 100 may control a moving operation to predict and avoid the unable-to-move situation and thus may provide a safer and more efficient robot movement environment.

For example, based on a common area included in each of a plurality of images (or frames) constituting at least one portion of input video, the preprocessor 1310-2 may generate one composite image by at least partially overlapping the plurality of images. In this case, a plurality of composite images may be generated from one video.

The model training unit 1310-4 may learn a criterion regarding how to determine a situation based on learning data. In addition, the model training unit 1310-4 may learn a criterion regarding which learning data to use for situation determination.

According to an embodiment of the disclosure, the model training unit 1310-4 may learn a criterion regarding which unable-to-move situation to estimate, based on context data regarding the unable-to-move situation having occurred.

In addition, the model training unit 1310-4 may train a data recognition model for use in situation determination by using learning data. In this case, the data recognition model may be a previously built model. For example, the data recognition model may be a model previously built by receiving basic learning data (e.g., a sample image).

The data recognition model may be built by taking into account a factor, such as an application field of the data recognition model, a purpose of learning, or computer performance of an apparatus. The data recognition model may be, for example, a model based on a neural network. For example, a model such as a deep neural network (DNN), a recurrent neural network (RNN), or a bidirectional recurrent deep neural network (BRDNN) may be used as the data recognition model, but the disclosure is not limited thereto. According to various embodiments of the disclosure, when there are a plurality of previously built data recognition models, the model training unit 1310-4 may determine a data recognition model in which input learning data and basic learning data have a high relevance as a data recognition model that will be trained. In this case, the basic learning data may be previously classified according to types of data, and the data recognition model may be previously built according to types of data. For example, the basic training data may be previously classified according to various criteria, such as an area where learning data is generated, a time when learning data is generated, a size of learning data, a genre of learning data, a generator of learning data, a type of an object within learning data, and the like.

In addition, the model training unit 1310-4 may train a data recognition model by using a learning algorithm including, for example, an error back-propagation method or a gradient descent method.

In addition, the model training unit 1310-4 may train a data recognition model, for example, via supervised learning with learning data as an input value. In addition, the model training unit 1310-4 may train a data recognition model, for example, via unsupervised learning in which a criterion for situation determination is discovered by learning by itself a type of data required to determine a situation without supervision. In addition, the model training unit 1310-4 may train a data recognition model, for example, via reinforcement learning using a feedback regarding whether or not a result of determining a situation according to learning is correct.

In addition, when a data recognition model is trained, the model training unit 1310-4 may store the trained data recognition model. In this case, the model training unit 1310-4 may store the trained data recognition model in a memory of an electronic apparatus including the data recognizing unit 1320. Alternatively, the model training unit 1310-4 may store the trained data recognition model in a memory of an electronic apparatus including the data recognizing unit 1320 described below. Alternatively, the model training unit 1310-4 may store the trained data recognition model in a memory of a server connected to an electronic apparatus via a wired or wireless network.

In this case, the memory storing the trained data recognition model may also store, for example, a command or data related to at least one other component of an electronic apparatus. In addition, the memory may store software and/or a program. The program may include, for example, a kernel, middleware, an application programming interface (API) and/or an application program (or “application”).

The model evaluating unit 1310-5 may input evaluation data to a data recognition model, and when a recognition result output from the evaluation data fails to satisfy a certain criterion, the model evaluating unit 1310-5 may allow the model training unit 1310-4 to perform training again. In this case, the evaluation data may be preset data for evaluating the data recognition model.

For example, when the number or percentage of pieces of evaluation data of which a recognition result is not accurate among classification results of the trained data recognition model for evaluation data exceeds a preset threshold, the model evaluating unit 1310-5 may evaluate a certain criterion as being unsatisfied. For example, in a case where the certain criterion is defined as 2%, when the trained data recognition model outputs wrong recognition results for more than 20 pieces of evaluation data among a total of 1000 pieces of evaluation data, the model evaluating unit 1310-5 may evaluate the trained data recognition model as being unsuitable.

When there are a plurality of trained data recognition models, the model evaluating unit 1310-5 may evaluate whether each of the trained data recognition models satisfies a certain criterion, and may decide a model satisfying the certain criterion as a final data recognition model. In this case, when a plurality of models satisfy the certain criterion, the model evaluating unit 1310-5 may decide any one preset model or a certain number of models in an order of higher evaluation score as the final data recognition model.
